What are the key points of winged bean cultivation techniques?
Winged bean is a perennial herbaceous plant in the subfamily Faboideae (Papilionoideae), and it is also a fairly well-known vegetable in China. Its tuberous roots, tender pods and leaves are all edible. Winged bean is rich in protein and fat nutrients, and it is widely cultivated in China. Growing winged bean is actually not very easy and requires a certain level of cultivation skill. So how should winged bean be cultivated? Below, the editor brings you the cultivation techniques for winged bean. Let's take a look!
1. Deep ploughing and land preparation
Before sowing, we must first choose a good planting plot. Winged bean has low requirements for soil, as long as the soil is not too barren or compacted and is free of pests and diseases. After choosing the planting site, prepare the land appropriately. Land preparation is done to improve soil permeability, enhance soil fertility and promote the growth of winged bean. When preparing the land, plough it about 30 cm deep, remove the weeds on the plot, and apply sufficient base fertilizer. The base fertilizer is mainly agricultural machinery fertilizer and phosphorus-potassium fertilizer. After deep ploughing, disinfect and expose the soil to the sun to eliminate germs and insect eggs in the soil and prevent them from harming the growth of winged bean.
2. Sow at the right time
Winged bean is extremely intolerant of cold, so we should sow after the temperature gradually rises in spring, preferably when the surrounding temperature is above about 20 degrees. One week before sowing, build a seedling bed, then lay plastic film to raise the temperature of the seedling bed, and water appropriately. When the water gradually seeps down, make the field beds and dig the planting holes. When sowing, put 2-3 seeds in each planting hole, and after sowing cover with fine soil and plastic film to keep warm. Before emergence, keep the temperature of the seedling bed at about 26 degrees to promote seed germination and emergence.
3. Transplanting and planting out
After emergence, increase the ventilation of the field and keep the seedling bed temperature at about 23 degrees; the nighttime temperature must not be lower than 15 degrees either. If the soil is too dry, water it in time, and as the temperature rises, gradually increase ventilation. When the average temperature stabilizes above 16 degrees, remove the plastic film. When the seedlings grow 3 true leaves, after about one month, they can be transplanted appropriately. Avoid rainy days when transplanting, and the temperature must not be lower than 15 degrees. Transplant the seedlings with soil, control the planting density well; the main planting method is ridge planting, which can not only ensure the healthy growth of winged bean but also raise the soil temperature.
4. Field management
During the seedling stage, winged bean grows very slowly, so we should regularly carry out intertillage and weeding to improve the soil's moisture-holding capacity. Winged bean is relatively sensitive to nitrogen fertilizer, so throughout its entire growth period, apply less nitrogen fertilizer, because the roots of winged bean have a strong nitrogen-fixing ability, and excessive nitrogen fertilizer will cause excessive vegetative growth of winged bean and reduce the flowering and pod-setting rate. Winged bean likes water relatively much, so water it regularly to keep the soil moist and prevent insufficient soil moisture content from affecting the growth of winged bean. However, water must not be excessive either; in rainy weather, do a good job of drainage.
The spacing between individual winged bean plants is very large, and the land utilization rate is relatively low, so in order to avoid wasting land resources, we can interplant some low-growing vegetables in the vegetable garden, such as rapeseed and so on. In addition, winged bean is a climbing plant, so after it enters the vine-extending stage, do a good job of setting up trellises and guide the vines onto the trellises at the right time.
